Diamondbacks acquired RHP Brad Ziegler from the Athletics for 1B-OF Brandon Allen and LHP Jordan Norberto. J.J. Putz and David Hernandez have been a late-inning solid tandem, but the acquisition of Ziegler provides Kirk Gibson with another reliable option. The 31-year-old has a 2.39 ERA and 29/13 K/BB ratio over 37 2/3 innings this season. He's making $1.25 million in 2011 and remains under team control through 2014. One wonders if parting with Allen means Paul Goldschmidt is on his way to the big leagues.
